Different hardness of RTV2 Silicone Moulds for Silicone Reborn Doll Mold

silicone rubber mold liquid rtv-2 for casting
We can provide liquid additional cure silicone rubber with different hardness.
1. For small size and dttailed pattern(within 30cm), 15-20 shore A can be applied, which is easy for de-molding and will not damage the patterns.
2.For the products with medium size, such as 50cm, 25-30 shore A silicone rubber should be used.
3.For products with large size, such as 1m, 35-40 shore A shall be recommend to avoid deformation.
4.If the product is large but features detailed pattern, 30 shore A silicone rubber will be workable.(It will be better to protect the products from deformation to make outer mold.)
Note: All the above products hardness should be adjusted according to customers' requirements.

 

Notice of Clear Two Part Liquid Silicon for  baby Dolls Mould Making

1.As it's easy to cause uncure problem, pls clean up all the tools which had mixed with condensation cure silicone rubber to avoide undure problem.
2.Do not add any pigment or powder into the addition cure silicone rubber before testing to prevent uncure problem.
3.Addition cure silicone rubber is biscomponent including part A and part B, do not add the part B on the container which had hold part A, the same for part B.
4.The mixing ratio(1:1 or 10:1) must in strict accordance with the ratio in case of the changing of the hardness.
5.The solidification is particularly affected by temperature

Questions To Confirm
Questions To Confirm With You.(In order to recommend you the most suitable products, pls help me check the following information. )
1. Which size of your products? 0-30cm, 30-50cm, or >50cm?
2. The operating method is pouring or brushing?
3. May i know your application? Make molds for which kinds of products?
4. May I know your requirements about the color? mixing ratio? operating time and curing time?
5. Do you have other requirements?

1. Why will the silicone mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which can destroy the molecular weight of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs or the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)

2. Why does the silicone mold get burnt out?
This consequence happens only because you have left out the important notes when using unsatured resin materials to produce your products. The unsaturated resin products great heat when added the curing agent. So you demould the resin product within 3 minutes can avoid this problem.

3. Why is the appearance of the finished mold striate and unsmooth?
The 3 reasons:
a.It is because the appearance of the product or the model itself is not perfect
b.The product or the model has not been polished before the further operation
c. You haven't spray the release agent evenly
So when you make silicoen molds, firstly you should choose a perfect mold and polish it, spray the release agent evenly on the product. In this case, the problem can be avoided.
